It was 100-degrees outside when I did it, so I just "kinda" cleaned up the old stuff, and cleaned the roof in the whole area with Keytone. Reason being, that I was using 6", and didn't have to worry about what was going on waay under it, just on the edges. Used a 2" wallpaper roller, which was all I could find at the time.
Worked well, but not pretty, since I dropped one end before I had a chance to line it up.
No second chances at 100+!
Still worked well.
